I was wondering some opinions on should i get one infinity kappa dvq 10, or 12. Or should I go with a rockford fosgate and get a 2 punch18inch 4ohm ones instead. I will probbabbly be playing Slipknot, to marvin gaye, and everything inbetween. I know the smaller the sub, the quicker it can bounce back for another note. I know the infinitys are worth it, sound wise. Are the fosgates worth looking at? thanks guys, and girls.
